Land snail richness and abundance along a sharp ecological gradient at two sampling scales: disentangling relationships

Popis výsledku v původním jazyce

It is generally recognized that the number of land snail species increases with the number of individuals in samples. This correlation may be an artefact of sample size, but it may also reflect the similarity in microhabitat preference of many species. Biotic interactions (competition) might also influence this relationship: an upper limit to co-existence at a particular scale. Here, we model the relationships between number of species, abundance of live individuals and environmental factors in the snail faunas of treeless fens covering a broad range of calcium content. The models considered two scales of sampling: (i) a 12 litre sample collected at a 4×4 m plot (187 samples) capturing at least 80% of the site's known species pool, and (ii) a samplingof 25×25 cm plots (115 samples) usually capturing less than 40% of the site's species pool. At the larger scale, the number of species responded to the calcium gradient more tightly than did total densities; but this was reversed at the s
